RYZEN 3000-SERIES CPUS – MEMORY AND FABRIC OVERCLOCKING
 Ryzen 3000-Series CPU’s Zen2 architecture allows for independent overclocking of the Infinity Fabric and
the Memory clock
‒ Typical memory overclocking performance up to 1866 MHz is most efficient with the fabric and memory clocks
coupled at 1:1 ratio
‒ Above a memory clock of 1866 MHz, turning Coupled Mode off and setting Fabric Clock to half the Memory Clock
will likely be necessary for further memory timing parameter optimization toward system stability*
